Water in the oil.Looks like a milk shake.Can someone tell me why?I know about a head gasket.Any other reasons?

 

Someone poured water in the crankcase? Sorry, man... 99% of the time its a head gasket. Do you have oily residue in your coolant?

 

head gasket sounds right, and not always is it oil in the coolant, I just finished a 3vze where the head gasket blew and coolant dumped into the oil, not the other way around. double check the block, if it is the 3.0L it may need to be decked where the heads mount to the block. it also fouled the upstream O2 sensor.

 

Running terrible.Checked the oil and it is more tan color and slippery feeling.Real nasty.Radiator is now low on water guess its all in the oil.But pulled the oil filler cap off and its milky big time.Pulled the valve cover today and its coated all over with this gunk.I know its head gasket but is there anything else that could put all that water mix together.Anything besides a head gasket.

 

I know how you feel, had bad HG, too recently
Just had my engine rebuilt for better performance, end reliability. That feels good

Yes,
Best case: someone poured water in the crankcase, like Mountain Cop said^^
Worst case: cracked head or block.

 

Could be your timing chain guide broke (long time ago) and the chain slapped and wore through the timing cover, opening up the coolant to flow into the oil pan.

See that pocket on the left side, just to the right of the large pipe? If the chain wears through that wall, it can let coolant seep into your oil pan.



Here's what the wear looks like with the chain with no guides to keep it in place:

 

Can also be a crack in the head. That's why a 'standard' valve job includes pressure-testing the head. Much less likely, though possible, is a crack in the block.

 

If the timing chain was rattling before, this could be the problem. You'll hear a rattling, buzzing noise when the engine starts and at certain RPMs. I'm currently driving a Nissan truck that does this. I'm hoping the Alaska DMV sends me the plates for the new '98 Taco truck sitting unused in my driveway before the Nissan chain wears through the block. It might be a close race. I agree that the headgasket is the most likely problem though.

 

Man great pics.Gonna take the head off tonight put it in the shop let them do what they need to.Chain and guides already been replaced not long ago.How can I tell if its the block.Sure not going to take that to the shop.I guess its the head gasket but want to cover all the bases.Never thought about the block.anyway that I can do that and what do I look for

 

Hey guys I forgot to thank all of you I appreciate everyones help.Just thought of a problem that may be big.When I take the head off drain antifreeze and the oil.What about all that nasty stuff still in the block.Heater core radiator.I can flush these with my garden hose along with the overflow tank.How do I get that junk out of the crankcae.All the bearings probably have that on them want to get that out.What about kerosene.I heard some oldtimer talk about that

 

new to forums this is a test GkN9U

 

I was looking through the forums and read about a coupla guys having leaks of coolant on that back plate on the cylinder head.Is there any way possible for that coolant to get in the cranckcae and cause this milkshake?

 

The engine will more than likely need a full rebuild. Once oil and water mix and it get's into your engine bearings, they will fail and sooner rather than later. Also, the oiling holes in the crank/block and probably head are full of that stuff too. There is only one way to get it all clean, and that is a full tear down. Like you said, the cooling system and heating system will need a full flush. If it was me, I would get a new radiator and heater core. But clean them first before condemning them...

 

If you put your engine in your signature, we can help further. If a 3vze there's an outside chance it's your factory oil cooler failing...

 

oh sorry about that. I thought I put the engine size in my post. I have the 22 are e motor. is there any way that plate on the back of the cylinder head that gasket underneath if it goes bad can that cause the antifreeze to get into the combustion chamber or would it just cause a leak
